Изобретение относитс  к очистке химическими способами и может быть использовано при очистке воды в осветлител х на водоподготовительных установках тепловых электростанций и промпредпри тнй.The invention relates to the purification by chemical methods and can be used in the purification of water in clarifiers in water treatment plants of thermal power plants and industrial enterprises.

Известен способ автоматнческого регулировани  процесса нзвесткованн  воды в осветлителе путем дозировани  известкового молока в зависимости от электропроводности обрабатываемой воды во входной зоне осветлнтеЛ  (1|.There is a method of automatic regulation of the process of water injection into the clarifier by metering milk of lime depending on the conductivity of the treated water in the inlet zone of the clarifier (1 |.

Нанболее близким к предлагаемому по технической сущности  вл етс  способ, регулировани  процесса известковани  воды путем изменени  дозы извести, подаваемой в обрабатываемую воду в зависимости от экстремального значени  электропроводности известкованной воДы в пробоотбориом потоке. {2}.Most closely to the proposed technical essence is the method of regulating the process of water lime by changing the dose of lime supplied to the treated water depending on the extreme value of the electrical conductivity of the lime water in the sampling stream. {2}.

Недостатком указанного способа  вл етс  то, что при его использовании 1юндуктометрические датчики из-за повышенного содержани  Э пробе механических примесей и хнмически активной среды либо изнашиваютс , либо на поверхност х измерительных  чеек накапливаютс  отложени , что снижает точность и надежность регулировани  и повышает затраты на обслуживание. Кроме этого, на абсолютную величину электропроводности существенно вли ют температурные и другие переменныеThe disadvantage of this method is that when it is used, the induction sensors, due to the increased content of E, the sample of mechanical impurities and the chemically active medium either wear out, or deposits accumulate on the surfaces of the measuring cells, which reduces the accuracy and reliability of control and increases maintenance costs. In addition, temperature and other variables significantly affect the absolute value of electrical conductivity.

исходные услови  (например, общее солесодержание исходной воды), что ограничивает область применени  нзвестного способа регулировани  на химводоочистках с переменными услови ми работы.baseline conditions (e.g., the total salt content of the source water), which limits the scope of application of the well-known method of control in water treatment systems with varying conditions of operation.

5 Целью изобретени   вл етс  повышение точности , надежности н Снижение эксплуатационных затрат..5 The aim of the invention is to improve the accuracy, reliability and decrease in operating costs.

Поставленна  цель достнгаетс  тем, что стабилизируют расход известкованной воды в JQ пробоотборном потоке, тнтруют эту воду исходной водой по экстремальному значению электропроводности получаемой смеси, и в зависимости от количества затраченной на титрооание исходной воды измен ют дозу подаваемой в обрабатываемую воду извести.This goal is achieved by stabilizing the consumption of lime water in the JQ sampling stream, tying this water with the source water according to the extreme electrical conductivity of the mixture obtained, and depending on the amount of source water spent on titration of the source water, lime is fed.

Изобретение по сн етс  чертежом.The invention is illustrated in the drawing.

Функциональна  схема регулировани  дл  осуществлени  предлагаемого способа содержит прОбоотборное устройство, включающее пробозаборную точку 1, установленную во входной зоне осветлител  2, смеситель 3 кондуктометрическогО титратора 4, в качестве которого применен экстремальный регул тор электропроводности с кондуктометрическим датчиком 5 на выходе из смесител , подключенным к регулирующему устройству экстремума 6, выход - которого через исполнительный механизм 7 соеThe functional control circuit for the implementation of the proposed method includes a sampling device, including sampling point 1 installed in the input zone of the clarifier 2, mixer 3, conductometric titrator 4, for which an extreme conductivity regulator is used with a conductometric sensor 5 at the mixer outlet connected to the control device extremum 6, output - which through the actuator 7 soy
